"Spirituality" is a term that has been used for centuries, and its meaning has evolved over the years. The term has been associated with the charisms of certain religious orders, such as the Carmelites or Franciscans of the Catholic Church or the Cabala of Jewish mysticism, and has represented the belief that an individual can be affected directly by a transcendent, divine spirit within the context of an established religious system. The experience of this spirit by the individual is facilitated by a disciplined life of prayer and, often, a spiritual guide. This leads to greater discernment about what path the individual should take to achieve enlightenment and union with God. There has been increased interest in spirituality over the past two decades, and the definition of this term has expanded to include experiences outside traditional religious settings. Nature-based spiritualities, such as Native American spirituality and eco-spirituality, are currently explored by individuals who feel alienated by the hierarchies of organized religion and feel reverence for the earth. The common thread in definitions of spirituality is the belief in a personal communion with what is holy through prayerful meditation and conscious living.
